Converting from Lambert (L) to Candela per Square Foot (cd/ft²) | Luminance

What is Lambert (L)

Lambert (L) is a unit of luminance used to measure the brightness of a surface emitting or reflecting light. It represents the amount of light emitted or reflected from a surface in a particular direction.

What is Candela per Square Foot (cd/ft²)

Candela per Square Foot (cd/ft²) is a unit of luminance that measures the intensity of light falling on a surface per square foot. It is a measure of the brightness perceived by the human eye.
